This grant funds an ambitious new project by the Chemical Heritage Foundation to build a free mobile app for iPad that recreates the excitement and educational potential of working with a chemistry set. Structured like a game, the app will instruct users in the principles of chemistry and guide them through a series of increasingly complicated virtual experiments that explore the properties of matter, thermodynamics, gases, and chemical energy. The app will be focused on 12 to 15 year olds and, when completed, will be available to download for free. The project is an experiment in how to leverage new developments in information technology and media to advance the public understanding of science.
